Unable to load saved game

Try starting the game without the memory card. If it starts up then you know that you have a bad memory card.

u should modify ur ps2 with modchip go to any electronic shop

try to reset your ps3 back to factory settings

Its a problem from the system. Try re-updating the console... to the latest firmware... then try playing the game. If that does not work... call in the PSN

the game saved data is corrupted

try callibrating tv game go to options>callibrate

Try another game see if it loads, im assuming it stopped playing the game, froze, or gave some sort of error right?

Your laser could be bad, that is my idea for the situation. Your laser probably loads to a certain point and then just stops for some reason. You can try adjusting the potentiometers up 10 percent if your technologically advanced or try and replace the whole laser/drive.

First of all, make sure the card is in slot one. I'm not sure about Guitar Hero 3, but I know many games default to searching the first slot (the one on your left as you look at the system).

Assuming that's not the problem, it could be a sign that your memory card is wearing out. Do you have a second memory card? If not, I suggest getting one. Either way, put one card in each slot, and go into the browser. Copy the Guitar Hero saves over to the other card, then put that card in slot 1 and see if it works. If it does, I suggest copying all your saved games over to the new card, and throwing the old one out before you lose any save games permanently.

Well maybe when you turn it on, it might be on manual mode. To switch it to auto mode, Press options then press the wrench and then find auto or manual mode and then, switch it to auto mode. Save the options and then it should play the game. If it doesn't work, blow into the DS game and then the DS game slot.
